The use of topiramate in mood stabilization

OBJECTIVE: To review data on the effectiveness of topiramate as a mood stabilizer. DATA SOURCES: Clinical literature accessed through MEDLINE (1985-September 2001) and the manufacturer. Key search terms included topiramate, mania, mood stabilizer, and bipolar disorder. DATA SYNTHESIS: The traditional standard therapy for bipolar disorder has been lithium. Other mood stabilizers are increasingly being used to manage this complex disorder. Studies that used topiramate in bipolar disorders were evaluated. CONCLUSIONS: The present data from open trials suggest that topiramate may possibly possess antimanic properties. Controlled, double-blind studies are required to confirm this efficacy

Gabapentin treatment for bipolar disorders

OBJECTIVE: To review the effectiveness data on the use of gabapentin in bipolar disorders. DATA SOURCES: Clinical literature was accessed through MEDLINE (January 1985–November 2000). Key search terms included gabapentin, mood stabilizer, and bipolar disorder. DATA SYNTHESIS: Bipolar disorder is a complex condition that can be difficult to treat effectively. Mood stabilizers are increasingly being used to manage bipolar disorder. Studies that used gabapentin in bipolar disorders are evaluated. CONCLUSIONS: From the data presented, gabapentin cannot be recommended for treatment of bipolar disorder. Further studies are required to determine whether gabapentin has any role in the management of bipolar disorder.
